Comet 79P Gehrels

Dear All
I don't usually take pretty pics but decided to use a little bit of clear sky from 2 nights ago to image this little comet. It was very close to the celestial equator at the time.
It doesn't seem to have much of a tail but does have a nice coma.

I just took 3 x 3min exposures through each of B, V and R filters (photometry filters) and combined them. I am pretty hopeless at post processing as I find it boring but have had a go. The 2 separate images are stacked differently. One is aligned on the comet and the other is aligned on the stars. As the comet is moving I cant align on both.
The images were taken with a VC200l and an ST10XME using an AO8 and guiding with a QHY guider.
